White drinking-grade PAC is an inorganic coagulant in powder form (light yellow powder, GB15892-2009), CAS 1327-41-9, used for coagulation, flocculation and water clarification. Features: fast flocculation, high activity and good filterability; no alkaline additive required; stable over a wide pH range; low residual salt in treated water; helps remove heavy metals. Typical specifications: Al2O3 ≥30% (typical 30.4%); basicity 40–90% (typical 46.7%); pH (10 g/L solution) 3.5–5.0. Applications: drinking water, industrial process water, municipal sewage and industrial wastewater (textile dyeing, paper, coal washing, electroplating, metallurgy, food processing). Packaging: 25 kg, 700 kg or 1000 kg bags. Store dry and cool; shelf life one year. Reference dosage (kg per 1000 t of water): domestic water 2.5–25; urban sewage 15–50; papermaking wastewater 50–300; printing and dyeing 100–300; electroplating 20–100; coal washing 30–100. Dissolve to a 3–5% solution (solid grade) before dosing.
